Material Notes:

Pyrocast AR is a fused silica castable refractory inert to liquid aluminum and its alloys. It is a high strength material offering resistance to erosion and mechanical damage. Parts cast from Pyrocast AR are heat-treated to ensure free and combined water are removed. Pyrocast AR floats in aluminum, minimizing the potential for refractory inclusions.ApplicationsHot-top table sections Transfer & stub troughs Launder linings Filter boxes Sheet ingot spouts Control pins Furnace tubes AdvantagesDimensionally stable Thermal shock resistant Easily cleaned Extremely durable Smooth cast surface Preheating unnecessary Non-wetting Information provided by Pyrotek.
